Solar Energy In Your Home
Article by Jeff Klein
Photovoltaic cells – those small black squares, a range of which comprises any solar panel – are getting more efficient, and gradually more affordable, thanks to design improvements which allows them to focus gathered sunlight on a very concentrated point. The dimensions of the solar cells is decreasing while their efficiency is steadily increasing, meaning that each and every cell becomes cheaper to manufacture while continually increasing its ability to capture solar energy. Regarding price, the cost of producing solar-generated energy per watt hour has come down to .00 at the time of this writing. Less than 20 years ago, that cost was nearly double.
Solar powered electricity generation is unquestionably good for the environment, especially if one subscribes to the theory of global warming. This alternative model of producing energy gives off absolutely zero emissions and uses probably the most naturally occurring of all things as it’s driver. Solar collection cells have turned out to be increasingly simple for homeowners and high occupancy building owners to place on their rooftops to collect solar energy. Also, these energy capture systems are not difficult to manage or use to make heat, create hot water, or produce electrical power. In the case of using the photovoltaic cells in typical residential hot water generation, the system works with the water while it is still encased in the cells. There it is heated and and then sent through the pipes.
Overcast and rainy days used to be a substantial obstacle for photovoltaic cell radiation collection. However, one company specifically, Uni-Solar, has developed photovoltaic collection arrays for the home that work effectively on inclement days, by way of a technologically more innovative system that collects more energy during sunlit days than previous systems or even other array designs.
There’s actually another solar panel system available for use called the PV System. This system works by connecting to the nearest electrical grid; whenever it detects an excess of solar energy being collected at a particular home, the energy transferred toward the grid for communal use which, in turn, becomes a viable means of lowering the grid’s dependence on hydroelectrically-driven power production. Being connected with the PV System can keep electricity costs down, while also alleviating the strain on the grid system. Solar energy has become the focus of many small towns and communities as they look to reduce costs and pollution.
We are now seeing quite a few big-name corporations making strides toward solar power production, storage and use (which further hints that solar generated energy is starting to become an economically feasible alternative energy source). Google is setting up a 1.6 megawatt solar power generation plant for the roof of it’s corporate headquarters, while Wal-Mart intends to put in an enormous 250 megawatt system of its own.
Nations such as Germany, Japan, the U.S., and Switzerland are furthering the call for solar energy manufacturing by providing federal subsidies or by way of giving tax incentives to companies that agree to utilize solar energy for generating its heat or electrical power. As technology advances and more storage is created, more private investors might find the value in trying out this
